2 Claims.

This invention relates to a machine for reducing pieces of ice to smallparticles or chips, one of the objects being to provide a simple andcompact structure of this type which can be manufactured at low cost,and when operated will quickly comminute the ice fed thereto.

A further object is to provide the machine with a chipping cylinderutilizing picks spirally arranged whereby the ice, while being subjectedto the action thereof, will be shifted from one end toward the other ofthe cylinder so that different portions of the piece of ice areconstantly being presented to the action of the picks.

Another object is to provide a machine which will produc chips ofuniform size.

With the foregoing and other objects in View whichwill appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings Figure 1 is a central vertical section through themachine taken from front to rear.

Figure 2 is a section on line 2Z, Fig. 1.

Figure 3 is a front elevation of the machine.

Figure 4 is a perspective view of a portion of the chipping cylinder andadjacent parts.

Figure 5 is an end elevation of the chipping cylinder, a portion of oneof the end guards being shown in elevation and a portion of the feedboard being illustrated in section.

Referring to the figures by characters of reference, l designates aninclined feed board having upstanding parallel side boards 2 all ofwhich cooperate to form a chute. A housing including a top 3, and endwall 4 and side pieces 5 is erected over a portion of the chute and isfixedly joined thereto and to a supporting frame 5 which can be suitablybraced as indicated at 6.

A table I is pivotally mounted at one end between the side boards 2 asshown at 8 and normally bears downwardly on the upper end of the feedboard I.

The lower or outlet end of the chute 9 formed by the feed board I andside boards 2 has a hinged cover it), while secured to the inner sidesof the side boards 2 directly opposite each other are arcuate guardstrips II which are concentric A cylinder I3 is mounted on the shaft 1-2and its ends are lapped by the guard strips II which thus serve toprevent particles of ice or the like from becoming lodged between theside boards and the ends of the cylinder. In order that these guards mayserve as deflectors they are tapered in the direction of the upper endof the chute, gradually increasing in thickness toward the cylinder.They can be formed of wood or any other suitable material and can be ofany size desired.

An annular groove M is formed in the periphery of the cylinder close toone end thereof and receives an endless belt l5 which extends throughopenings l6 in the top of the housing, the upper portion of this beltbeing engaged and driven by a pulley IT on, the shaft l8 of a motor 19supported on the top 3.

The cylinder I3 is sheathed preferably with sheet metal as indicated at20 and extending through this sheathing and into the cylinder are picks2! in the form of short spikes each of which is pitched at an angle tothat radius of the drum extending therethrough, all of the picks thusbeing inclined in the direction of rotation of the drum as clearlyindicated in Fig. 5. The picks are arranged in spiral rows extendingaround the drum as shown in Fig, 2 and all of them are adapted to moveclose to the upper surface of the feed board I. In practice the cylinderis rotated at a high speed in the direction indicated by the arrow inFig. 5 so that the picks will plow downwardly through any materialbrought thereagainst. The block of ice to be chipped is placed on thetable 1 and is there broken into pieces substantially of a predeterminedsize. These pieces are then placed in the chute 9 and will move bygravity along the feed board l until they come into the paths of therotating picks. The picks of each row will successively plow through andchip the ice, sweeping these chips downwardly through the pass betweenthe cylinder and the feed board so that the particles delivered from thelower or outlet end of the chute will be substantially of uniform size.As the picks are spirally arranged, they will engage the ice atdifferent points and will tend to shift the ice from one end to theother of the cylinder during the chipping operation.

The size of the chips produced can be regulated by increasing orreducing the size of the pieces of ice supplied to the cylinder.

ice every one-half inch transversely of the'chute and by making the passbeneath the cylinder not more than nine-sixteenths of an inch at'itsmore restricted points, approximately twoand one half gallons of chippedice can be produced per minute.

The motor can be plugged into any convenient electric service outlet andas the entire apparatus is very simple in construction there are noparts which can readily get out of order. The driving belt is protectedat all times from the action of the ice because of the location-of theguard in irontthereof.

What is'olaimed is:

1. An ice chipping machine including an includingan inclined troughhaving-an upper inlet and a lower outlet, a transverse :shaft journaledin the trough, a rotatable cylinder mounted on the shaft and extendingtransverselywithin the trough,spirally arranged series of picks embeddedin and projecting from the cylinder, said picks being pitched in thedirection of rotation of the cylinder and beingproportioned andpositioned to move close to the bottom of the trough, a motor, a drivingbeltoperatively connecting the motorrto the cylinder, said cylinderhaving a groove in one end for the reception of the belt arcuate guardstrips disposed adjacent to' the ends of the cylinder, within thetrough, one of the guards being positioned in front of the belt andgroove.

2. An ice chipping machine including an inclined trough having an upperinlet and a lower outlet, a transverse cylinder in the trough, aprotecting sheathing extending around the cylinder,

spirally arranged series of picks extending through the sheathingandinto the cylinder, allof the picks being pitchedin the direction ofrotation of the cylinder, said cylinder having an annular groove in oneend, and said trough con- :stitutingmeans for feeding ice by gravityinto the paths of the picks, said picks being positionedtosuccessivelymove into position close to the-bottom of the trough, amotor, a belt connectionbetween themotor and the cylinder, said "beltconnection being seated in the groove, and

arcuate deflecting guards in the side portions of v the trough andlapping those portions of the cylinder nearest the inlet, said guardsconstituting ice deflectors and. one of the :guards. constitutingashield for the-belt connection.
